ATTACHMENT FOR RUBBER-STOCK MACHINES.

Specification of Letters Patent.

Patented. Oct. c, 1908.

Application filed August 16, 1907. Serial No. 388,894.

To all whom it may concern:.

Be it known that I, LIDA A. VVELLs, a citizeness of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and use ful Improvements in Attachments forRubher-Stock Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in attachments for use inconnection with machines for manufacturing rubber stock.

The object of the invention is to provide an attachment of thischaracter by means of which rubber stock may be guided and fed to thecylinders or rollers of the machine, thereby avoiding the danger of theoperators being caught and injured by the rollers.

With this object in View, the invention consists of certain novelfeatures of construction, combination and arrangement of parts as willbe more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a side view of a portion of arubber stock machine, showing the construction and arrangement of theinvention; Fig. 2 is a front view; and Fig. 3 is a vertical longitudinalsectional view of the same. I

Referring more particularly to the draw ings, 1 denotes a portion of arubber stock machine, in the standards, 2, of which are revolublymounted calendering pressing rolls, or cylinders, 3.

The attachment, 4, comprises supporting standards, 5, on the upper endsof which are revolubly mounted rolls, 6, which are adapted to engage theupper calendering roll, and thereby steady the machine. Between thestandards, 5, is secured a feed chute, 7 which is preferably in the formof a fiat, rectangular box, and is disposed'at an angle in thestandards, 5, as shown. The chute 7 is preferably provided with suitablegage devices, 8, by means of which'stock of various widths may be runthrough between the rolls or cylinders of the machine. The total widthof the chute is equal to the length of the calendering rolls, so thatstock of the width of the rolls may be run through. The adjustment ofthe box for various widths of stock is provided for by the gages, 8,hereinbefore described.

Inconnection with the chute I provide a bearing brackets, 10, projectingoutwardly from the standards 5, and is disposed adjacent to the outerend of the chute, whereby the-stock will pass freely through the latterwhen fed to the calendering rolls. The roller,

9, is shown in the drawing as a loosely mounted idle roller. The samemay, however, if desired, be geared up and driven from any of the movingshafts of the calendering machine.

By means of an attachment such as herein shown and described, the stockmay be fed to the rolls of a calendering machine without danger of theoperators being caught and injured thereby.

I-Iavingthus fully described my invention, what I claim as new anddesire to secure by Letters-Patent, is:

' 1. A device of the character described, comprising a pair ofsupporting standards adapted to be arranged adjacent to the rollers of acalendering machine, steadying rollers journaled in the upper end ofsaid standards and adapted to bear against the upper rollers of saidmachine, an inclined feed chute arranged between said standards, gagedevices to regulate the width of said chute, and a guide rollerrevolubly mounted adjacent to the outer end of said feed chute,substantially as described.

2. An attachment for rubber stock machines, comprising a 'pair ofsupporting standards adapted to be arranged adjacent to the rolls ofsaid machine, said standards being independent or of separateconstruction from said machine, a pair of steadying rollers revolublymounted on the upper ends of said standards and adapted to be engagedwith the upper roll of the machine, a guide roller revolubly mounted inthe lower portion of said standards and arranged transversely betweenthe same, an inclined feed chute secured between said standards, saidchute comprising a fiat box-like structure open at its upper and loweredges, spacing strips arranged in said chute, and means to secure saidspacing strips in adjustable positions therein, whereby the width of theguiding space ofthe chute is regulated, substantially as described.

3. An attachment for rubber stock machines, ,comprising a pair ofsupporting standards adapted to be arranged adjacent to the rolls ofsaid machine, said standards being independent or of separateconstruction from said machine,- a pair of steadying rollers revolublymounted on the upper ends of said standards and adapted to be engagedwith the upper roll of the machine, a guide roller revolubly mounted inthe lower portion of said standards and arranged trans versely betweenthe same, an inclined feed chute secured between said standards, saidchute comprising a fiat box-like structure open at its upper and loweredges, and provided in its upper side with transversely disposed slots,spacing strips arranged in said chute transversely of said slots, boltssecured to said strips and adapted to project upwardly through saidslots, and clamping nuts adapted to be secured onto said bolts wherebysaid strips are held in adjusted position in said chute to vary theguide strips thereof, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
